CROSS REFERENCE TO RELATED APPLICATIONS

This application is related to and claims priority from the following U.S. patents and patent applications. This application is a continuation of U.S. application Ser. No. 17/029,821, filed Sep. 23, 2020, which is incorporated herein by reference in its entirety.

BACKGROUND OF THE INVENTION 1. Field of the Invention

The present invention relates generally to a system and a method for converting power from a first direct current power source with a first voltage to provide power to at least one other direct current power source with at least one different voltage.

2. Description of the Prior Art

The military uses various types of portable electronic devices (e.g., radios) and batteries used to power portable electronic devices. Radios are one example of mission critical devices that must be powered at all times. However, not all of these portable electronic devices and batteries use the same operating voltage. It is known in the prior art to provide direct current (DC)-DC converters.

Representative prior art patent documents include the following:

U.S. Patent Publication No. 20170229692 for material for dissipating heat from and/or reducing heat signature of electronic devices and clothing by inventors Thiel, et al., filed Mar. 27, 2017 and published Aug. 10, 2017, is directed to systems, methods and articles having a heat-shielding or blocking, heat-dissipating and/or heat signature-reducing material layer or coating. In one example, the heat-shielding or blocking, heat-dissipating and/or heat signature-reducing material completely covers the interior of a housing having a plurality of battery cells removably disposed therein. Other examples include a heat-shielding or blocking, heat-dissipating and/or heat signature-reducing material layer having anti-static, anti-radio frequency (RF), anti-electromagnetic interference (EMI), anti-tarnish, and/or anti-corrosion materials and properties that effectively protect battery-operated devices and/or the batteries that power them from damage or diminished operation.

U.S. Pat. No. 6,545,890 for flanged terminal pins for dc/dc converters by inventor Pitzele, filed Dec. 19, 2000 and issued Apr. 8, 2003, is directed to a dc/dc converter mounted to a printed circuit board with rigid terminal pins which extend into a converter substrate to provide electrical connection to circuitry on the substrate. A terminal pin includes a flange which abuts the printed circuit board and spaces the converter substrate from the printed circuit board. Connection to the printed circuit board is made by solder provided between the flange and the circuit board.

U.S. Pat. No. 6,894,468 for control of DC/DC converters having synchronous rectifiers by inventors Bretz, et al., filed Jul. 7, 2000 and issued May 17, 2005, is directed to a DC to DC power converter including synchronous rectifiers which respond to a control waveform. Negative current from a load into the power converter is prevented by increasing the converter output voltage at a minimum current limit. The synchronous rectifiers may be held off in response to decision logic by activation of a hold-off circuit connected to a control terminal of a synchronous rectifier or of an ORing transistor at the converter output. When the synchronous rectifier is subsequently enabled, its control waveform may be increased slowly relative to the switching cycle.

U.S. Pat. No. 7,050,309 for power converter with output inductance by inventor Farrington, filed Dec. 5, 2003 and issued May 23, 2006, is directed to the duty cycle of a primary winding circuit in a power converter that causes near continuous flow of power through the primary and secondary winding circuits during normal operation. By providing no regulation during normal operation, a very efficient circuit is obtained with a synchronous rectifier in the secondary operating at all times. However, during certain conditions such as start up or a short-circuit, the duty cycle of the primary may be reduced to cause freewheeling periods. To simplify the gate drive, the synchronous rectifiers may be allowed to turn off during the freewheeling periods, resulting in large ripple. A filter inductance of the secondary winding circuit reduces that ripple, and is sufficient to minimize ripple during normal operation, but still allows large ripple during the freewheeling periods. By accepting large ripple during other than normal operation, a smaller filter inductance can be used.

U.S. Pat. No. 7,787,261 for intermediate bus architecture with a quasi-regulated bus converter by inventors Farrington, et al., filed Nov. 1, 2007 and issued Aug. 31, 2010, is directed to a dc-dc converter system that comprises a quasi-regulated bus converter and plural regulation stages that regulate the output of the bus converter. The bus converter has at least one controlled rectifier with a parallel uncontrolled rectifier. A control circuit controls the controlled rectifier to cause a normally non-regulated mode of operation through a portion of an operating range of source voltage and a regulated output during another portion. The bus converter may be an isolation stage having primary and secondary transformer winding circuits. For the non-regulated output, each primary winding has a voltage waveform with a fixed duty cycle. The fixed duty cycle causes substantially uninterrupted flow of power during non-regulated operation. Inductors at the bus converter input and in a filter at the output of the bus converter may saturate during non-regulated operation.

U.S. Pat. No. 8,720,762 for load carrier systems and associated manufacturing methods by inventors Hilliard et al., filed Jun. 17, 2011 and issued May 13, 2014, is directed to load carrier systems and associated manufacturing methods. The patent discloses that a load carrier system can include a unitary piece of material. The unitary piece of material can include a body portion comprising a first face side, an opposing face side, a first peripheral edge and an opposing second peripheral edge; and one or more straps comprising a respective extended end, wherein the straps are an integral part of the body portion; wherein the one or more straps are folded over onto the first face side adjacent to the first peripheral edge; and wherein at least one respective end of the one or more straps is fastened to the opposing second peripheral edge.

The present invention is generally directed to a system and a method for converting power from a first direct current power source with a first voltage to provide power to at least one other direct current power source with at least one different voltage.

In one embodiment, the present invention provides a direct current (DC)-DC conversion system including at least one DC source, at least one source cable, wherein each of the at least one source cable includes a source input connector, a source output connector, and a source input cable electrically connecting the source input connector with the source output connector, a DC-DC converter, wherein the DC-DC converter includes a housing, a DC-DC input connector, and a DC-DC output connector, at least one output cable, wherein each of the at least one output cable includes a load input connector, at least one load output connector, and a load input cable electrically connecting the load input connector with the at least one load output connector, and at least one DC load, wherein the housing is configured to store electronics, wherein the electronics include a printed circuit board (PCB), and wherein the PCB is configured to designate at least one output voltage, wherein the DC-DC converter is operable to receive energy from the at least one source via the at least one source cable, wherein the source input connector is operable to electrically connect to the at least one source, and wherein the source output connector is operable to electrically connect to the DC-DC input connector, wherein the DC-DC converter is operable to provide energy to the at least one load via the at least one output cable, wherein the DC-DC output connector is operable to electrically connect to the load input connector, and wherein one or more of the at least one load output connector is operable to electrically connect to one or more of the at least one DC load, and wherein the at least one source cable includes a helicopter source cable.

In yet another embodiment, the present invention provides a direct current (DC)-DC conversion system including at least one DC source, wherein the at least one DC source includes a vehicle battery, at least one source cable, wherein each of the at least one source cable includes a source input connector, a source output connector, and a source input cable electrically connecting the source input connector with the source output connector, a DC-DC converter, wherein the DC-DC converter includes a housing, a DC-DC input connector, and a DC-DC output connector, at least one output cable, wherein each of the at least one output cable includes a load input connector, at least one load output connector, and a load input cable electrically connecting the load input connector with the at least one load output connector, at least one DC load, and a battery protector, wherein the battery protector is electrically connected to the vehicle battery and the DC-DC converter, wherein the housing is configured to store electronics, wherein the electronics include a printed circuit board (PCB), and wherein the PCB is configured to designate at least one output voltage, wherein the DC-DC converter is operable to receive energy from the at least one source via the at least one source cable, wherein the source input connector is operable to electrically connect to the at least one source, and wherein the source output connector is operable to electrically connect to the DC-DC input connector, wherein the DC-DC converter is operable to provide energy to the at least one load via the at least one output cable, wherein the DC-DC output connector is operable to electrically connect to the load input connector, and wherein one or more of the at least one load output connector is operable to electrically connect to one or more of the at least one DC load, wherein the at least one source cable includes a helicopter source cable, and wherein the battery protector prevents draining of the vehicle battery.

Team operations in remote locations, such as military operations, require radios to allow team members to communicate about danger, injuries, opportunities, etc. Without radios in these environments, more people would be injured or die. These operations also require other equipment (e.g., amplifiers, wearable batteries, smartphones, tablets) to allow team members to communicate, survey the environment, etc. The radios and other equipment typically require lithium ion batteries. However, the lithium ion batteries may not be able to the power the radios and other equipment for the time necessary to complete the operation on a single charge. As such, a portable power supply may be required to recharge the lithium ion batteries.

Further, not all equipment and batteries operate using the same supply voltage. What is needed is a DC-DC conversion system that is operable to provide a DC voltage to at least one electronic device (e.g., battery, radio) using at least one charging device. Additionally, there is a long-felt unmet need for a DC-DC conversion system that is able to harvest energy from typically unused sources including, but not limited to, a helicopter (e.g., UH-60).

To achieve multiple scavenging tips coordinating with multiple outputs to gear and/or batteries, DC-DC conversion systems of the prior art either (1) simplify the system down to one cable so that it can only collect from one source and deliver the correct energy to one battery or device, thereby losing flexibility in the field, or (2) make the system maximally complex and flexible such that an operator must program the inputs on a central DC-DC “power manager” device, which causes a loss of situational awareness as the operator looks down at the power manager device to plug the correct cable into the correct marked port, thus distracting the operator from combat. Thus, an operator has had to choose between simplicity of use or maximum flexibility, either sacrificing flexibility or simplicity and speed of operation. The present invention unites flexibility with simplicity by putting the complexity inside a housing and not requiring a user to program anything, and by making a three-part cable that an operator assembles simply and quickly, without having to learn or read which parts to use. Modularity provides flexibility and also makes it possible to only carry the input and output cable sections that are necessary for the mission at hand, saving weight, expense, and further simplifying the system.

Further, the present invention rapidly dissipates heat from the DC-DC converter to prevent operators from getting burned by the DC-DC converter. The barrel housing of the DC-DC converter incorporates imbedded copper high speed heat dissipating vacuum tubes to dispel heat away from the DC-DC converter safely.

Additionally, extremely low retention connectors near the operator facilitate rapid transition from mounted to dismounted without getting clotheslined or tangled in the charging cables. The battery or device cables on the output end are easily identified by touch even in low light or no light situations because the size of the connector is unique to a voltage. For example, big connectors work with higher voltages, while lower voltages correspond to smaller connectors.

None of the prior art provides a DC-DC conversion system that is operable to provide a DC voltage to at least one electronic device (e.g., radio, battery) using at least one charging device including, but not limited to, a helicopter (e.g., UH-60) while providing advantages including simplicity and flexibility as described above.

Certain aspects of the presently disclosed subject matter of the invention, having been stated hereinabove, are addressed in whole or in part by the presently disclosed subject matter, and other aspects will become evident as the description proceeds when taken in connection with the accompanying illustrative examples and figures as best described herein below.

Referring now to the drawings in general, the illustrations are for the purpose of describing a preferred embodiment of the invention and are not intended to limit the invention thereto.

System

FIG. 1 illustrates a block diagram of one embodiment of a DC-DC conversion system 100. In the embodiment shown in FIG. 1 , a DC-DC converter 200 is operable to receive energy from at least one source via at least one source cable. The at least one source includes, but is not limited to, an XX90 source cable 300 connected to an XX90 battery, a North American Treaty Organization (NATO) source cable 400 connected, e.g., to a NATO ground vehicle, an alligator clip source cable 500 connected, e.g., to a vehicle battery, a male cigarette source cable 600 connected, e.g., to a cigarette lighter socket in a vehicle, a 152/148 battery source cable 700 connected to a battery operable to power, e.g., a PRC-152 radio or a PRC-148 radio, a helicopter source cable 800 connected to, e.g., a UH-60 helicopter (i.e., Black Hawk), and/or a conformal wearable battery source cable 900 connected to, e.g., a NETT WARRIOR battery. In one embodiment, a voltage range of the at least one source is automatically any voltage between 9 VDC and 40 VDC.

The DC-DC converter 200 is operable to provide energy to at least one load via at least one output cable. Each of the at least one output cable includes a load input connector connected to the DC-DC converter and at least one load output connector connected to at least one load (e.g., rechargeable battery, wearable battery, portable power case, radio, electronic device). The at least one output cable includes, but is not limited to, a 17V output cable 1000, a 30V output cable 1100, a 12V output cable 1200, a 34V output cable 1300, a 17V and 30V dual output cable 1400, a 12V and 17V dual output cable 1500, a 30V and 34V dual output cable 1600, a 12V, 17V, and 30V triple output cable 1700, and/or a 17V quadruple output cable 1800.

The at least one load is preferably a battery or a power source (e.g., portable power case) rather than another type of electronic device (e.g., radio). Advantageously, charging a battery or a power source allows for maximum flexibility when using any other type of electronic device (e.g., radio). For example, if the DC-DC converter is used to charge a battery, the battery is operable to power a radio, a laser designator and/or rangefinder (e.g., a Special Operations Forces Laser Rangefinder Designator (SOFLAM)), a tablet, a smartphone, a satellite phone, a thermal imaging device, or any other type of electronic device.

In a preferred embodiment, a voltage output of the DC-DC converter is arranged via pin out of the load input connector. This is in contrast to “smart cabling”, which is not robust enough for soldiers to use in the field.

Preferably, the diameter and/or shape of each of the at least one load output connector of an output cable is different for different output voltages. In one example, a first load output connector has a higher output voltage (e.g., 29.4V (“30V”)) and larger diameter, while a second load output connector has a lower output voltage (e.g., 16.8V (“17V”)) and smaller diameter. This coordination of higher voltage with larger diameter and lower voltage with smaller diameter makes it intuitive for an operator to use the correct output connector for the correct device (e.g., rechargeable battery, wearable battery, portable power case). Advantageously, this coordination allows an operator to associate the correct output connector with the correct device in the dark. Thus, each of the at least one output connector on an output cable is an inherent voltage selector. Further, the operator can quickly connect devices without knowing an operating voltage, thereby maintaining situational awareness and eyes on combat.

FIG. 2 illustrates a block diagram of the DC-DC conversion system. The DC-DC converter is preferably a three-component system: (1) at least one source cable each having a source input connector operable to matingly connect to a DC source (e.g., via a DC source connector), a source input cable, and a source output connector operable to connect to a DC-DC input connector of a DC-DC converter; (2) the DC-DC converter with a housing for electronic components and further including the DC-DC input connector operable to matingly connect to the source output connector, a DC-DC input cable, and a DC-DC output connector operable to matingly connect to a load input connector of an output cable; and (3) at least one output cable each with the load input connector operable to matingly connect to the DC-DC output connector, a load output cable, and a load output connector operable to matingly connect to a DC load (e.g., via a DC load connector). Energy flows from the DC source to the DC load. The DC load is preferably a rechargeable battery operable both to receive and discharge energy simultaneously. Thus, the DC load is both operable to power a device (e.g., a radio) while be charged using the DC-DC conversion system.

DC-DC Converter 200

FIG. 3 illustrates one embodiment of the DC-DC converter 200. In a preferred embodiment, the DC-DC converter includes a housing 210 and a DC-DC input cable 220 with a DC-DC input connector 230. In one embodiment, the DC-DC input cable 220 is permanently fixed to the DC-DC converter. In an alternative embodiment, the DC-DC input cable 220 is removably attachable to the DC-DC converter. A dust cap 240 protects the DC-DC input connector 230 from environmental elements (e.g., dust, sand) when not in use, which could cause equipment failure in the field. In one embodiment, the DC-DC input connector 230 is a slip away connector. In another embodiment, the DC-DC input connector 230 is a FISCHER SOV A105 A087 connector. Alternatively, the DC-DC input connector 230 is a locking connector. In a preferred embodiment, the dust cap 240 is molded into a boot of the DC-DC input connector 230.

The DC-DC input connector 230 preferably exclusively mates to the source output connector on the source cable, thus eliminating confusion in how to connect the three-component system. Advantageously, this allows an operator to easily discern between connectors in the dark. Additionally, this allows the operator to quickly connect devices while in combat, thereby maintaining situational awareness.

FIG. 4A illustrates an angled view of a housing 210 of one embodiment of a DC-DC converter. FIG. 4B shows an end view of the housing 210 of one embodiment of a DC-DC converter. FIG. 4C shows a side view of the housing 210 of one embodiment of a DC-DC converter. FIG. 4D shows a cross-section of the housing 210 of one embodiment of a DC-DC converter.

As best seen in FIGS. 4A-4B and 4D, the exterior of the housing 210 preferably has fins 280 to dissipate heat (i.e., a heat sink). The fins 280 provide a larger surface area to dissipate the heat. Additionally, or alternatively, the housing of the DC-DC converter is formed of copper vacuum tubes encased in an aluminum extrusion. Copper has a high thermal conductivity, which allows heat to quickly dissipate, and aluminum provides a weight savings.

The housing 210 preferably is hollow to allow electronics to be stored within a cavity 290 in the DC-DC converter. The electronics preferably include a printed circuit board (PCB). In a preferred embodiment, the PCB designates at least one output voltage (e.g., two output voltages, three output voltages, four output voltages, five output voltages, six output voltages, etc.). In one embodiment, the PCB designates four different output voltages. In one embodiment, the four different output voltages are operable to be selected sequentially. In one embodiment, one or more of the at least one output voltage is not programmed. In one example, a first output voltage is 17V, a second output voltage is 30V, and a third output voltage and a fourth output voltage are not programmed. Advantageously, this allows retrofitting of the DC-DC converter to the voltage of future devices.

In one embodiment, the electronics include a buck-boost regulator that converts an input voltage to an output voltage. In one embodiment, the DC-DC converter employs synchronous rectification to produce a high conversion efficiency. In a preferred embodiment, the DC-DC converter has an input voltage range of between about 9V and about 40V. Alternatively, the DC-DC converter has an input voltage range of between about 5V and about 50V. In one embodiment, the DC-DC converter has an output voltage range of between about 0V and about 40V. In one embodiment, the buck-boost regulator has a current of 15 A.

The DC-DC converter preferably includes an input under-voltage lockout to protect the DC-DC converter at low input voltages.

In yet another preferred embodiment, the DC-DC converter includes a thermal shutdown to protect the DC-DC converter from high temperatures (e.g., greater than or equal to 115° C.).

While designing the DC-DC converter, it was attempted to use a ¼ brick. However, the ¼ brick was not able to handle the load needed. The design was modified to use a ½ brick, which worked, but was hot enough to burn a user when it was touched. As a result, it was impossible to place in a polymer or a plain metal housing. If heat dissipation was done using only fins, the fins would be too long and it would be impractical to carry the housing. However, by inserting the copper vacuum tubes, the fin size was able to be reduced by half. This advantageously reduces the diameter of the housing by half and is acceptable to an end user.

FIG. 6 illustrates an orthogonal view of the output end of the DC-DC converter 200.

In one embodiment, the DC-DC converter includes a panel mount strain relief to be a right-angle adapter. Advantageously, this embodiment prevents the DC-DC converter from hitting an operator on the head when using a utility receptacle 28 VDC on a helicopter, which is located on the ceiling above the operator's head.

Additionally or alternatively, the battery protector is a low voltage disconnect (LVD) that automatically disconnects the load when the vehicle battery voltage falls below a set DC voltage (e.g., 10.6V, 10.8V, 11.0V, 11.2V, 11.4V, 11.6V, 11.8V, 12.0V, 12.1V, or 12.2V fora 12V battery or 19V, 20V, 21V, 21.4V, 22V, 22.5V, 22.8V, 23V, 24V, 24.2V, 25V, or 25.5V for a 24V battery). In one embodiment, the battery protector automatically reconnects the load when the battery voltage returns to a normal value (e.g., above the set DC voltage) after charging. The battery protector automatically detects the vehicle battery voltage (e.g., 12V or 24V) and selects a corresponding set DC voltage (e.g., 11.6V for a 12V battery or 22.8V for a 24V battery) in another embodiment.

As previously mentioned, the DC-DC converter preferably has an input voltage range of between about 9V and about 40V. This is particularly advantageous with respect to batteries for military radios (e.g., AN/PRC-152), which do not have a low voltage cutoff. As a result, it is possible to drain the battery below the operating range of the battery. Other DC-DC conversion systems include an input voltage range beginning at 5V, which is disadvantageous because this will drain the battery below the operating range of the battery and render the battery unusable. Therefore, the system of the present invention provides a cost savings by not rendering expensive military batteries unusable. There is a long-felt, unmet need for a system that protects military batteries from being drained below the operating range of the battery.

Helicopter 800

The system preferably includes a helicopter source cable 800 operable to connect to a utility receptacle 28 VDC. The utility receptacle 28 VDC is present on a helicopter (e.g., UH-60 Black Hawk). Advantageously, the utility receptacle 28 VDC allows for operators to charge the at least one device using the system. For example, the system allows a radio operator to ensure that a battery used to power a radio is fully charged before the radio operator is dropped off for a mission. As a duration of the mission can vary, ensuring the battery is fully charged before drop off protects the radio operator and other soldiers from prematurely losing communications.

In a preferred embodiment, the load input dust cap 1050 is molded into a boot of the load input connector 1010.

To make the modified TAJIMI R04-P5m connector, a locking ring on a TAJIMI R04-P5m connector is replaced with a floating aluminum guard to protect the connector contact block, but still allow the connector to slip away. This was developed specifically to allow the slip away connector to mate with a DC load connector (e.g., on a portable battery pack) in a non-locking fashion, such that an operator can charge a battery on the portable battery pack while in a vehicle, yet achieve unimpeded, rapid egress if dismounting were suddenly required. Other connectors were attempted to be used with the present invention, but were used exclusively as a charging connector, which reduced flexibility and increased the number of connectors to learn and wear. Advantageously, the modified TAJIMI R04-P5m connector allows an operator to have full capability of in/out power on each connection to the DC load.

As previously mentioned, the 17V output connector 1030 is preferably a slip away connector to allow for rapid egress in mounted to dismounted operations.

In one embodiment, the DC-DC conversion system includes a 17V and 34V dual output cable. Other output voltages (e.g., 40V) are compatible with the DC-DC conversion system.

In one embodiment, the DC-DC conversion system includes at least one triple voltage output cable. In a preferred embodiment, the at least one triple voltage output cable is operable to sequentially charge a first device (e.g., a first rechargeable battery) with a first voltage (e.g., 12V), a second device (e.g., a second rechargeable battery) with a second voltage (e.g., 17V), and a third device (e.g., a third rechargeable battery) with a third voltage (e.g., 30V). Alternatively, the at least one dual output cable is operable to simultaneously charge the first device with the first voltage (e.g., 12V), the second device with the second voltage (e.g., 17V), and the third device with the third voltage (e.g., 30V).

FIG. 25 illustrates one embodiment of a 7-pin connector (e.g., FISCHER S104 A054). In one embodiment, the 7-pin connector is connected to a 4-core cable. In one embodiment, a first wire and a second wire of the 4-core cable are connected to a first pin and a second pin (e.g., Pin 1 and Pin 2), respectively, and a third wire and a fourth wire of the 4-core cable are connected to a third pin and a fourth pin (e.g., Pin 5 and Pin 6), respectively. Advantageously, this allows the output cable to provide two output voltages.

In another embodiment, the 7-pin connector is connected to a 6-core cable. In one embodiment, a first wire and a second wire of the 6-core cable are connected to a first pin and a second pin (e.g., Pin 1 and Pin 2), respectively, a third wire and a fourth wire of the 6-core cable are connected to a third pin and a fourth pin (e.g., Pin 4 and Pin 5), respectively, and a fifth wire and a sixth wire of the 6-core cable are connected to a fifth pin and a sixth pin (e.g., Pin 3 and Pin 6), respectively. Advantageously, this allows the output cable to provide three output voltages.

The system needs to remain simple and intuitive, with operators not having to learn the voltages of their batteries and gear. To maintain this simplicity, the preferred embodiment of the system requires an output cable with multiple voltages to employ only one output voltage at a time. Preferably, only a single device (e.g., rechargeable battery) is connected to the DC-DC converter at a time. The single device determines which voltage is employed.

In another embodiment, the DC-DC conversion system is programmed with a list of preferred voltages. For example, if a first device with a first voltage (e.g., 12V), a second device with a second voltage (e.g., 17V), and a third device with a third voltage (e.g., 30V) are all connected to the DC-DC converter via a triple voltage output cable, the DC-DC conversion system defaults to charge the second device (e.g., 17V), then the third device (e.g., 30V), and then the first device (e.g., 12V).

In yet another embodiment, the DC-DC converter divides the power output such that all connections are recharging at least two devices simultaneously, but at a lower current than a single device would be charged.

Advantageously, this coordination allows an operator to associate the correct output connector with the correct device in the dark. Thus, the output connector is an inherent voltage selector. Further, the operator can quickly connect devices without knowing an operating voltage, thereby maintaining situational awareness and eyes on combat.
